A <scp>DRD</scp> 4 gene by maternal sensitivity interaction predicts risk for overweight or obesity in two independent cohorts of preschool children

Abstract

Many children who carry the 7R allele of DRD4 appear to be more influenced by maternal sensitivity as it relates to overweight/obesity risk, consistent with a plasticity effect. Given the relatively small sample sizes available for these analyses, further replications will be needed to confirm and extend these results.
